Should you sleep in underwear or without? The honest answer
Short answer: there is no single right answer, but the honest one is that going without underwear overnight, or wearing a loose breathable pair, lets the area stay cool and dry while you sleep, which most experts consider mildly beneficial. If you prefer wearing underwear to bed, choose a breathable pair with a cotton-lined gusset and put on a fresh one. As always, the real factor is breathability and staying dry, not a strict rule.
Is it better to sleep without underwear?
For a lot of people, yes, mildly. Sleeping without underwear lets the skin breathe and stay dry overnight, which suits a warm environment or anyone prone to feeling damp. It is a preference more than a medical instruction. If you sleep more comfortably with nothing on, that is a perfectly healthy choice, and there is no downside for most women.
What if you prefer to wear underwear to bed?
Also fine. The trick is to make it breathable and fresh. A pair with a cotton-lined gusset and a breathable knit lets air move and keeps you dry, and changing into a clean pair for bed rather than wearing the day's is the part that actually matters. Avoid anything tight or non-breathable overnight, because that is the only thing that creates the warm, damp environment worth avoiding.
Does going without underwear at night prevent infections?
The evidence here is weak and often overstated. There is no strong proof that sleeping commando prevents infections, but the logic that dryness and airflow are good for that skin is sound. So it may help some people feel fresher, without being a guaranteed medical benefit. If you get recurrent issues, that is worth raising with your GP rather than treating underwear as the cure.
The bottom line
Do what is comfortable. Without underwear, or in a loose breathable pair, is the marginally airier choice. If you wear underwear to bed, make it breathable, cotton-gusseted and fresh. The principle is the same one that runs through all of this: dry and breathable beats damp and trapped.
For the daytime hours, we make one seamless pair built on exactly that principle, the Anywhere G, from $21.90 a pair in packs.
